{"product_id":"edwards-fx-pdd-duct-smoke-detector","title":"Edwards FX-PDD Duct Smoke Detector","description":"The Edwards FX-PDD is an intelligent addressable photoelectric duct smoke detector designed to detect smoke within HVAC ductwork and provide early warning while helping prevent smoke circulation through a building. It uses photoelectric light-scattering technology with differential sensing and environmental compensation for reliable detection. The detector supports rotary addressing, self-diagnostics, dirty detector identification, and a magnet-activated test switch. It operates across a wide air velocity range and includes visible status LEDs, a cover monitor switch, and a Form C auxiliary alarm relay for interfacing with HVAC controls or other equipment. The compact housing is less than 2 inches deep, making it suitable for installations where space is limited.","brand":"Edwards","offers":[{"title":"Default Title","offer_id":53117043540288,"sku":"FX-PDD","price":154.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/2274\/8736\/files\/FX_PDD_0_N.jpg?v=1788877574","url":"https:\/\/store.greenwaveelectronics.com\/products\/edwards-fx-pdd-duct-smoke-detector","provider":"Green Wave Electronics","version":"1.0","type":"link"}
